    Abstract: This invention provides an electrode electrolyte for a solid polymer-type fuel cell, in which a cost problem and a problem related to recovery of catalyst metals are solved, having excellent proton conductivity, dimensional stability and heat resistance. An electrode electrolyte for a solid polymer electrolyte-type fuel cell contains a polymer, which has a polyphenylene structure as a main chain and both a sulfonic acid group and a nitrogen-containing heterocyclic group as a side chain. A side chain having the nitrogen-containing heterocyclic group has a structure represented by the following general formula (D) . (In formula, Z represents at least one kind of structures selected from a group consisting of a direct bond, -O- and -S-, Y represents at least one kind of structures selected from a group consisting of -CO-, -SO 2 -, -SO-, -CONH-, -COO-, -(CF 2 ) l - (l is an integer of 1 to 10) and -C(CF 3 ) 2 - and R 20 represents a nitrogen-containing heterocyclic group. q represents an integer of 1 to 5 and p represents an integer of 0 to 4.) The above nitrogen-containing heterocyclic group is at least one kind of group derived from a compound selected from the group consisting of nitrogen-containing heterocyclic compounds including pyrrole, thiazole, isothiazole, oxazole, isoxazole, pyridine, imidazole, imidazoline, pyrazole, 1,3,5-triazine, pyrimidine, pyridazine, pyrazine, indole, quinoline, isoquinoline, purine, benzimidazole, benzoxazole, benzothiazole, tetrazole, tetrazine, triazole, carbazole, acridine, quinoxaline and quinazoline and derivatives thereof.
